The heart test I had was a stress echo cardiogram (supine bike) which showed hypokinesia of 1 out of 17 myocardial segments. I was told I may have minor coronary disease but the test showed low risk, basically a weak muscle. Even though there is a poor heart history in my family I don't worry about it, I can't change it and it hasn't been flagged as a problem. Mind you, if cardiology is anything like endocrinology then I'm totally up a gum tree
What lung tests did you have? Big machine with various breathing manoeuvres? Big glass box? Did it take 30-60 minutes altogether? That would be the full lung function tests. Or just spirometry?
If you've not had the full tests (you can Google for full lung function tests, some area's hospitals describe what is involved), then I would ask for them, also ask for a CT scan.
If I had been left with the initial diagnosis of COPD and not been referred to a respiratory consultant following pleurisy, pneumonia and several flare ups of colonised pseudomonas, then I would not have had the scan and diagnosis of bronchiectasis.
My GP (who has a special interest in lungs) guessed it might be bronchiectasis but it was the scan that provided the proof. It's not changed my treatment at the moment - two inhalers (bronchodilator and a long acting reliever), plus maintenance antibiotic three times a week to try and prevent infection, but it's actually good to know what it is and when a doctor or nurse brings up the fact that I used to smoke donkeys years ago (and basically blames me) I can now say that it can be caused by damage to lungs from childhood illnesses and think to myself 'up yours'
I would certainly following up in your shoes, we Hypos have enough to put up with!
